Sec. 1.3. Solve systems of linear equations by using row operations to put the augmented matrix into row-reduced form. This includes recognizing when an augmented matrix is in row-reduced form, and interepreting an augmented matrix to yield the solutions.

Sec. 1.4. Find the inverse of a matrix when possible, solve a system of linear equations using the inverse.

Sec. 2.1. Graph the region that corresponds to a system of linear inequalities.

Sec. 2.2. Set up a linear programming problem: identify the variables, write an equation for what is to be maximized or minimized, write the constraints as a system of inequalities.

Sec. 2.3. Solve a linear programming problem by the procedure on p. 68.
